An Irish woman has been charged with stabbing her fiance to death at their home in Sydney.

David Walsh (29), from Enniscorthy in Co Wexford, was discovered with a stab wound to his neck in the early hours of Saturday morning following an earlier altercation.

He was treated by paramedics but died at the scene.

The victim is a father of three girls and he is origianlly from Enniscorthy, Co Wexford. Locals said he emigrated to Sydney in recent years.

Mr Walsh, who works in construction, announced his engagement to Tina Cahill on Facebook last month, saying: “Here’s to the new chapter.”

According to local paper The Daily Telegraph, Mr Walsh's fiancee Ms Cahill was arrested at the scene with another man.

Police in Sydney have confirmed that the 25-year-old woman has since been charged with murder.

She has been refused bail and will appear in Parramatta Local Court on Sunday.

A 36-year-old man, from Revesby, is still being questioned at Bankstown Police Station.

Bankstown detectives are being assisted by officers from the State Crime Command’s Homicide Squad.

Bankstown Police crime manager Glen Fitzgerald told the Daily Telegraph that two other women were also at the home when a second man, who was known to the women, arrived at the house and an argument broke out.

“All five people are known to each other, ­albeit one of those males only tonight,” Supt Fitzgerald said.

“Four of them seem to live at this address.

“One of the males was at an establishment with them earlier in the day.”

New South Wales Police Force is working with the Irish Consulate in Sydney.

Enniscorthy councillor John O'Rourke told Independent.ie: "The town of Enniscorthy is numbed by this tragedy. He was a respected and talented young gentleman who worked in the building trade.

"David grew up in Moran Park in the town, the son of highly respected builder John Walsh and his wife Anna. He was one of six children. David leaves behind three daughters.

"I've known him since he was a child. I managed an under-12 team at Ajax Athletic football club and he was a handy young player. In his early 20s, he played for Enniscorthy United."

Mr O'Rourke said he joined residents of the town in extending sympathy to David's family and friends "at this very sad time". The victim had four brothers and one sister.

A spokesperson for the Republic's Department of Foreign Affairs said it was aware of the case and was providing consular assistance to the family of the victim.
